Product Description

Vishay Semiconductors VOT8024AM Optocoupler

The VOT8024AM is a high-performance optocoupler featuring a GaAs IRLED coupled to a zero-crossing TRIAC, packaged in a space-saving SOP-4 package. It provides robust isolation between low-voltage logic and AC mains (120 VAC, 240 VAC, 380 VAC), enabling control of various loads like motors, solenoids, and relays. Key advantages include high static dV/dt, low input current sensitivity, and a zero voltage crossing detector for reduced EMI.
